Can we say this means "sometimes the GSM modem stays awake"? Maybe you
can sniff it in the frequency domain to watch the kind of frequency
fingerprint you see from its activities.

Do we take care about the state of the GSM modem with regards to UART
traffic (ie, +++AT commands) as well as GPIO during these tests?

Hm we were down to 2mA the other day without GSM, what has happened? Is
it just these tests do not have those changes yet?
